Abstract. Water intake is an essential element of the water supply complex, normal operation of which depends on the quality of the water delivered to the consumer. Therefore, the water supply system should be effectively protected from various contaminants from the source, ice slurries, and juvenile fish. The authors analyze the operation of existing coarse screen devices in channel water intakes; identify their main disadvantages, such as: mechanical jamming (clogging) of the screen holes with debris, leading to its failure and the need to replace, as well as the laborious cleaning and the high cost of screen materials. The article notes that during operation there is an increase in the pressure drop affecting the screen due to the accumulation of a large amount of contaminants on its surface, which could lead to a throughput and a significant amount of pollution. To improve the quality of filtered water and operating conditions, the authors proposed to provide porous pipes installation instead of flat removable screens in the receiving section of the intake well. The material for their manufacture is a polymer concrete, based on crushed granite stones or gravel and a polymer bin
